摘要
滑坡是造成山区长输油气管道破坏的主要地质灾害之一。为了合理有效地评估山区油气管道的滑坡灾害风险,保障山区长输油气管道的安全,本文提出了基于改进层次分析法(IAHP)和逼近理想解排序法(TOPSIS)的山区油气管道滑坡灾害风险评估模型和方法,建立了考虑滑坡与油气管道相互作用等评估指标,选取了中缅油气管道典型滑坡灾害点进行应用分析,结果表明该段油气管道的滑坡灾害风险值为0.355,属于中风险,与现场调查情况一致。该方法可用于山区油气管道地质灾害风险排查和安全管理工作。
Landslide is one of the main geological disasters causing the damage of long-distance oil and gas pipelines in mountainous areas.In order to reasonably and effectively evaluate the landslide risk of oil and gas pipelines in mountainous areas and ensure the safety of long-distance oil and gas pipelines in mountainous areas.In this paper,the risk assessment model and method of landslide disaster of oil and gas pipeline in mountainous area based on Improved Analytic Hierarchy Process(IAHP)and approximate ideal solution ranking method(TOPSIS)are proposed.The assessment indexes considering the interaction between landslide and oil and gas pipeline are established.The typical landslide disaster points of China Myanmar oil and gas pipeline are selected as an example for application analysis.The results show that the landslide disaster risk value of this section of oil and gas pipeline is 0.355,which belongs to medium risk,Consistent with the field investigation.This method can be used for geological disaster risk investigation and safety management of oil and gas pipelines in mountainous areas.
